The firm, with offices in New York and Greenwich, Connecticut, said in the letter it received a search warrant and subpoena last week and met with the U.S. Attorney’s Office on Nov. 23. Investigators confirmed today it wasn’t a target of the investigation, according to a letter sent to investors.

“Nor, in fact, has the firm been alleged to have engaged in any misconduct or wrongdoing,” Level Global said in the letter, a copy of which was obtained by Bloomberg News.

The roughly $4 billion Level Global is run by David Ganek, a veteran of Steven A. Cohen’s SAC Capital.

Correction (10:48 a.m.): An earlier version of this story said that Level Global attributed last week’s raid to an investigation of one of its employees. Level Global did not mention any employee in its communication regarding the investigation.
